Ja, alle Titel der Gilmore-Gilrs Folgen sind Anspielungen auf Filme, Lieder oder so, manchmal natürlich leicht umgeändert.
Zu diesem bestimmten Zitat bei TV.com gefunden:
Episode Title: I’d Rather Be In Philadelphia
The title of this episode is also the title of a 2003 movie starring Patrick Warburton.
It was also an epitaph W.C. Fields proposed for himself in a 1925 article in Vanity Fair . It refers to his long standing jokes about Philadelphia (his actual birthplace), and the grave being one place he might actually not prefer to be. It has also sometimes been distorted into a final dig at Philadelphia: „Better here than in Philadelphia.“
